In the present embodiment, the convex portion 71D is used to separate a part of the contact region 2S from one surface 71A, but in addition, for example, the convex portion 71D is not provided and only the concave portion 71E is provided for contact. A part of the region 2S may be separated from one surface 71A.

When the soft capsule 2 absorbs moisture, the surface of the soft capsule 2 becomes sticky and easily adheres to one surface 71A, so that it becomes difficult to remove the soft capsule 2 from the storage container 1.
On the other hand, in the present embodiment, as a result of providing the convex portion 71D and the concave portion 71E as described above, the contact area between one surface 71A and the soft capsule 2 is reduced, so that the resistance acting on the soft capsule 2 is reduced. , The soft capsule 2 becomes easy to move. Therefore, even if the soft capsule 2 absorbs moisture, it can be easily taken out from the storage container 1.

More specifically, the surface of the soft capsule 2 tends to soften and the surface tends to become sticky under high temperature and high humidity.
When the storage container 1 is unopened and a hygroscopic agent such as silica gel is contained inside the storage container 1, the soft capsule 2 is difficult to absorb moisture. However, after opening the storage container 1, the soft capsule 2 may absorb moisture even if a hygroscopic agent is contained. In such a case, the soft capsule 2 adheres to one surface 71A, and it becomes difficult to remove the soft capsule 2 from the storage container 1.
On the other hand, in the configuration of the present embodiment, the adhesive force acting between one surface 71A and the soft capsule 2 is reduced, and the soft capsule 2 can be easily taken out.

In the present embodiment, the contact region 2S of the soft capsule 2 comes into contact with the portion of one surface 71A of the heat fusion layer 71, which is indicated by reference numeral 4E in FIG. Specifically, in the present embodiment, the contact region 2S comes into contact with the top portion 71P of the convex portion 71D.
Further, in the present embodiment, the sum of the areas of the top 71P (the sum of the areas of each of the plurality of tops 71P with which the contact region 2S contacts) is the portion of the contact region 2S that is separated from one surface 71A. It is smaller than the area.

In other words, in the present embodiment, the area of the contact portion in contact with one surface 71A of the contact region 2S of the soft capsule 2 is the separated portion separated from the one surface 71A of the contact region 2S. It is smaller than the area.
In this case, the drag force acting on the soft capsule 2 becomes smaller than the case where the area of the contact portion is larger than the area of the separated portion, and the soft capsule 2 becomes easier to move.

Further, in the present embodiment, as shown in FIG. 6A, each of the convex portions 71D is formed in a quadrangular pyramid shape having four ridge lines 71Q extending radially from the top portion 71P. Further, FIG. 6B shows a state when the convex portion 71D is viewed from the side, and the top portion 71P of the convex portion 71D has a curvature and is formed so as to draw a gentle arc. ..

The cross section shown in FIG. 5 shows the cross section taken along the line VV of FIG. 6A, and as shown in FIG. 5, each of the convex portions 71D is directed from the top portion 71P toward the base material layer 72. It has an extending ridge line 71Q and is formed in a quadrangular pyramid shape.
In other words, each of the convex portions 71D has a side portion 71R extending toward the substrate layer 72 and inclined with respect to the substrate layer 72. In other words, the side portions 71R of each of the convex portions 71D are provided with an inclination.

When the convex portion 71D is formed in a quadrangular pyramid shape as described above, when the side portion 71R of the convex portion 71D is not inclined as in other configuration examples of the convex portion 71D shown in FIG. In comparison, the contact area between the soft capsule 2 and the convex portion 71D becomes smaller, and the soft capsule 2 becomes easier to move.
In the present embodiment, the case where the convex portion 71D has a square pyramid shape has been described as an example, but the shape of the convex portion 71D is not limited to this, and other polygonal pyramids such as a triangular pyramid and a pentagonal cone are used. Alternatively, it may be a cone, or another polygonal pyramid or cone such as a square pyramid, a triangular pyramid, or a pentagonal pyramid whose top 71P of the convex portion 71D forms a substantially flat surface.

Further, in the present embodiment, as shown in FIG. 5, a gap 71V is formed on the side opposite to the accommodation space 16 with one surface 71A (inner surface 1X) sandwiched in the place where the convex portion 71D is formed. There is.
Specifically, in the present embodiment, an intermediate layer 73, which is another layer different from the heat fusion layer 71, is provided, and is intermediate with the heat fusion layer 71 corresponding to the place where the convex portion 71D is formed. A gap 71V is formed between the layer 73 and the other surface 71B and the intermediate layer 73.
In the present embodiment, the void 71V protects the soft capsule 2 from the impact acting on the soft capsule 2.
Further, since the void 71V functions as a heat insulating layer, the temperature in the accommodation space 16 is kept constant. Since the gap 71V can effectively prevent the soft capsule 2 from being softened by the influence of the temperature change of the outside air even when the storage container 1 is placed under high temperature conditions, one surface 71A And the soft capsule 2 are in close contact with each other, and it does not become difficult to take out the soft capsule 2.
For these reasons, it is preferable that the void 71V is formed.

From the viewpoint of forming the void 71V, it is more preferable to form each of the first laminated body 50 and the second laminated body 60 by the dry laminating method. Even if each of the first laminated body 50 and the second laminated body 60 is formed by the extrusion laminating method, the void 71V is formed, but the first laminated body 50 and the second laminated body 50 by the extrusion laminating method are formed. Comparing the laminated body 60 with the first laminated body 50 by the dry laminating method and the second laminated body 60, the first laminated body 50 and the second laminated body by the dry laminating method in which the void 71V is remarkably formed are formed. Body 60 is more preferred.

Further, at least, the adhesive layer adjacent to the heat-sealed layer is preferably laminated by the dry laminating method.
Regardless of the presence or absence of the printed layer and the intermediate layer, if at least the adhesive layer adjacent to the heat-sealed layer is formed by the dry laminating method, the effect of the void 71V can be obtained.
In other words, in the present embodiment, it is preferable that at least the second adhesive layer 76 of the first laminated body 50 and the second laminated body 60 is laminated by the dry laminating method.
The first adhesive layer 75 may be laminated by any known loading method such as a dry laminating method or an extruded laminating method, but the second adhesive layer 76 may be laminated by a dry laminating method. In the case of laminating by the dry laminating method, it is preferable that the first adhesive layer 75 is also laminated by the dry laminating method from the viewpoint of manufacturing efficiency.

When the first adhesive layer 75 and the second adhesive layer 76 are laminated by the dry laminating method, they are used for forming the second adhesive layer 76 rather than the amount of the adhesive used for forming the first adhesive layer 75. It is desirable to increase the amount of adhesive applied.

In the present embodiment, the heat-sealed layer 71 is provided with irregularities, and the adhesive area between the heat-sealed layer 71 and the intermediate layer 73 becomes small. Therefore, between the heat-sealed layer 71 and the intermediate layer 73. Adhesive strength tends to decrease.
In this case, as in the present embodiment, the thickness of the second adhesive layer 76 (the amount of the adhesive applied to the portion of the second adhesive layer 76) is set to the thickness of the first adhesive layer 75 (the thickness of the first adhesive layer 75). If it is thicker than the amount of the adhesive applied to the portion), it becomes easy to secure the adhesive strength between the heat-sealing layer 71 and the intermediate layer 73.
The preferable range of the amount of the adhesive applied to the first adhesive layer 75 is 2.0 to 3.5 g / m ² , and the preferable range of the amount of the adhesive applied to the second adhesive layer 76 is 3.0 to 6.0 g. / M ² .

In this embodiment, the case where the shape of the convex portion 71D in the front view is a rhombus has been described as an example, but the rhombus is an example, and the heat fusion layer 71 has a convex portion 71D having another shape. May be provided.
Specifically, for example, the shape of each of the convex portions 71D in the front view may be a square. Further, the shape of each of the convex portions 71D in the front view may be a polygon other than a quadrangle or a circle.

Further, the linear convex portion 71D may be provided, and the concave portion 71E may be provided in the region surrounded by the linear convex portion 71D.
Further, in providing the linear convex portion 71D, the width of the convex portion 71D may be reduced and the convex portion 71D may be provided at a higher density.

〔Example〕
The configuration of the laminated body 50X (the same laminated body as the first laminated body 50 and the second laminated body 60 shown in FIGS. 5 and 6) is as follows.
(1) Structure of laminated body 50X: base material layer 72 / printing layer 74 / first adhesive layer 75 / intermediate layer 73 / second adhesive layer 76 / heat fusion layer 71
(2) Details of each layer Base material layer 72: Polyethylene terephthalate film (thickness: 12 μm)
Printing layer 74: Printing ink for gravure printing First adhesive layer 75: Two-component curable urethane adhesive intermediate layer for dry laminating 73: Aluminum foil (thickness: 7 μm)
Second adhesive layer 76: Two-component curable urethane adhesive for dry laminating Heat-sealing layer 71: Embossed film made of linear low-density polyethylene (LLDPE) (thickness T: 70 μm, shape of convex portion 71D and concave portion 71E) : Shape shown in Fig. 5)

(3) Manufacturing Method Gravure printing was performed on one surface 72A of the base material layer 72 to form a printing layer 74.
Next, an adhesive was applied onto the print layer 74, and the base material layer 72 having the print layer 74 and the intermediate layer 73 (aluminum foil) were bonded together by a dry laminating method.

Next, an adhesive was applied to the surface of the intermediate layer 73 facing the heat-sealed layer 71, and the heat-sealed layer 71 was bonded by a dry laminating method to obtain a laminated body 50X.

[Comparative example]
In the comparative example, as the heat-sealing layer 71, straight-chain low-density polyethylene (thickness T: 60 μm) having no irregularities was used.
A laminated body was prepared in the same manner as in the configuration of the example except that the linear low-density polyethylene having no unevenness was used.

〔Experimental result〕
A laminated body 50X and a laminated body of a comparative example were prepared, a soft capsule 2 was placed on the laminated body, and an experiment was conducted to examine the rolling condition of the soft capsule 2. As a soft capsule, a commercially available "traditional garlic egg yolk" manufactured by Kenkoukazoku Co., Ltd. was used.
Specifically, a 100 mm (horizontal) × 200 mm (vertical) laminated body was prepared, and the four corners of the laminated body were fixed to an A4 size stainless steel plate using an adhesive tape.

The soft capsule 2 was immersed in tap water at room temperature for 1 minute, and then the water on the surface of the soft capsule 2 was wiped off.
Next, the soft capsule 2 was placed on a laminate fixed to a stainless steel plate. Then, as shown in FIG. 9 (a diagram illustrating the procedure of the experiment), one end 11A side of the stainless plate was lifted, and the angle θ of the stainless plate when the soft capsule 2 started to roll was measured.

FIG. 10 is a table showing the experimental results.
Three experiments were performed for each of the examples and comparative examples. In the example, the average value of the three experiments (the average value of the angle θ) was 16 °, whereas in the comparative example, the result was 45 °.
That is, in the embodiment, since the contact area between the soft capsule 2 and the heat-sealed layer 71 is relatively small, the adhesive force acting between the soft capsule 2 and the heat-sealed layer 71 is small, and the angle θ of the stainless steel plate is large. When small, the soft capsule 2 began to roll.
On the other hand, in the comparative example, since the contact area between the soft capsule 2 and the heat-sealed layer 71 is relatively large, the adhesive force acting between the soft capsule 2 and the heat-sealed layer 71 is large, and the angle of the stainless steel plate is large. The soft capsule 2 did not roll unless θ became large.
